Ax is a baby dragon horse from the village of Gordius. When Nick becomes an official member of the cavalry, Ax will be his horse, although the two are pretty much partners already. Ax is known to be a unique dragon horse because he has three horns on his heads and because of his restlessness and curiosity. Among dragon horses, curiosity is a sign of intelligence, so Ax is expected to be something special. - Matt620 (article), Basel (image)
